Synopsis The Science of Sanskrit Grammar and the Science of Sanskrit Poetics have played two distinct and significant roles in the development of Sanskrit language and Sanskrit literature.  Sanskrit Grammar is characterized by a good number of different schools.  Among those the most prominent is the school of panini.  Three earliest authorities of the said school or system of grammar viz., panini, Katyayana and Patanjali are given the status of seers.  The scope of Sanskrit Grammar is not confined to the problem of words, meanings and sentences.  It has a much wider field than that.  Eminent grammarians of the paninian School like Patanjali and Bhartrhari contributed many important philosophical views on different aspects of grammar, which have produced deep impact in the minds of prominent thinkers associated with many other branches of literature.  Great authorities on Sanskrit Poetics have expressed clearly about their indebtedness to Sanskrit Grammar.  The present work shows as to how closely the said two lores of learning viz., Sanskrit Grammar and Sanskrit Poetics are related.  It explains as to how far the Sanskrit Poeticians or Aesthetes, right from Bharata to Panditaraja Jagannatha, are influenced by Sanskrit Grammar in general and the Paninian system of grammar in Particular.
